Effect of HimCal Supplementation on Milk Yield of Dairy Cows MilkYield Before Supplementation, L During Supplementation, L After Supplementation, L Low 4.75 ± 0.00 5.46a ± 0.08 5.52a ± 0.03 Medium 9.42 ± 0.02 10.18a ± 0.12 10.68a ± 0.03 High 14.84 ± 0.04 15.68a ± 0.16 16.43a ± 0.03 aDiffers significantly (P < .01) frombefore HimCal supplementation. Low milk yield group: In this group, HimCal improved milk yield by 14.94% during and after supplementation period compared with that in the presupplementation period (P < .01). Medium milk yield group: In this group, HimCal improved milk yield during and after supplementation period by 8.06% compared with that in the presupplementation period (P < .01). High milk yield group: In this group, HimCal improved milk yield during and after supplementation period by 5.66% compared with that in the presupplementation period (P < .01). The improved milk yield trend continued even after the withdrawal of HimCal supplementation in all 3 groups. HimCal is a polynutrient formulation manufactured and marketed by Himalaya Wellness Company (Bengaluru, Karnataka, India). HimCal contains Mouktika Sukti (comprises calcium, phosphorus, and vitamin D3), Jivanti (Leptadenia reticulata), and Shatavari (Asparagus racemosus). The ingredients of HimCal possess galactopoietic action. The study results Objective To assess the effect of HimCal supplementation on milk yield of lactating dairy cows Materials and Methods This feeding trial was conducted in 28 cows (17 crossbred Holstein Friesian and 11 crossbred Jersey cows) of different age groups belonging to farmers in and around Bengaluru (Karnataka, India). The cows were individually penned and fed with native grass hay and concentrates. Ad libitum fresh and clean water was provided throughout the trial period. Based on milk yield, the cows were divided into 3 groups: low yield (0–6 L), medium yield (6–12 L), and high yield (> 12 L) groups. All the cows were supplemented (drenched/mixed with feed) with 100 mL HimCal, daily, for 10 days. The cows were hand milked, twice daily, at 6 to 7 AM and 5 to 6 PM, and the daily milk yield was recorded accordingly. Milk yield was recorded 7 days before HimCal supplementation, 7 days during supplementation (10 d), and 7 days after supplementation. The same cows were considered for comparison (control group). Data on feed intake and refusals were recorded on a daily basis. Any sign of estrus manifestation was visually observed and recorded. Cows in heat were artificially inseminated after 7 to 8 hours of observed estrus. The data collected were statistically analyzed using one-way ANOVA followed by Dunnett’s multiple comparison test using GraphPad Prism version software (GraphPad Software Inc, San Diego, CA, USA). Results and Discussion HimCal supplementation improved milk yield in dairy cows (Table). Efficacy of HimCal® Supplementation in Improving Milk Yield in Lactating Dairy Cows Research at Himalaya HimCal is a natural calcium and phosphorus feed supplement derived from oyster shell and has a higher bioavailability.
